Full text of "The manufacture and properties of iron and steel"

trouble was experienced through dust, although these difficulties have been, in great measure, overcome.
The plant of De Wendel at Hayingen is an example of the system of spare mills, as four complete mills, each with its modern German multiple cylinder engine, stand waiting their turn to run, for there are only men enough to run two mills and only steel enough for that number, in spite of the fact that they are operated in a very slow manner. The building covering these mills includes all the hot beds, finishing machines, storage and loading yards, and is, perhaps, 700 feet by 1000 feet, not including the converting department. The output is about 400 tons per day.
Table XXIY-E gives a list of the steel works and blast furnaces.

SEC. XXIVc.—The Ruhr:
The Ruhr district embraces most of Westphalia and a little of the western shore of the Rhine. It is here we find the coal that gives the best coke on the continent of Europe, though it is not equal to the coke of Durham or of Connellsville. The Ruhr coal district measures fifty miles square, being shown on the map in black with Ruhrort on the western end and Horde on the east, but coal is found east of Horde as far as Hamm and extends westward across the Rhine, several mines having recently been opened on the western bank. The works of Krupp at Essen are almost in the center. The deposit covers an area equal to the county of Westmoreland in Pennsylvania or the Durham, coal field in northeast England, but Westmoreland raises only ten million tons of coal per year, Durham about forty-six million and Westphalia nearly sixty million. The production of coke in the Ruhr is the same as in
